Introduction
The Analog Smoke/LPG/CO Gas Sensor (MQ - 2) module utilizes an MQ-2 as the sensitive component and has a protection resistor and a potentiometer on board.
The MQ-2 gas sensor is sensitive to LPG, i-butane, propane, methane, alcohol, Hydrogen and smoke.
It could be used in gas leakage detecting equipment in family and industry.
The resistance of the sensitive component changes as the concentration of the target gas changes.
Package Included
